Reading Remote Signal and LQ values to MicroScan graphs |
Each remote allows several status signals to be accessed to indicate the remote's operation
These figures can be seen in the list of parameters for the base, they are also "free access" and do not count toward dongle settings
Connected status shows Healthy (value=1) for connected and Faulty (value=0)
for Not Connected
Signal % gives the RX signal at the remote in % (ranges from 0-about 99%). If
the site has two or more remotes, it is possible for the RX signal to jump
between different levels as the remote takes different signal paths back to the
base.
Link Qual % gives the connection quality. This would normally be 100% unless the
base and remotes are having difficulty connecting.

The
RX signal/LQ values are read by the microscan driver and this has a 15 second
cache on the values so continuous reads will only update every 15 seconds.
The Connected status is updated from the bases node list, read by the driver
once per minute. A time delay is engaged after the remote is removed from the
node list in case of random short duration losses.
